Understanding CenturyLink and Quantum Fiber
What is Price for Life?
Price for Life is Quantum Fiber's unique guarantee that your monthly rate will never increase as long as you maintain service. Unlike competitors who raise prices after 12 months, Quantum Fiber customers pay the same rate indefinitely. This can save hundreds of dollars over time compared to providers with annual price increases.
CenturyLink vs. Quantum Fiber
CenturyLink DSL is the legacy service using phone lines, with speeds up to 140 Mbps. Quantum Fiber is the modern fiber-to-the-home service with symmetrical speeds up to 8 Gbps. Where available, Quantum Fiber offers significantly better value and performance.
